1.3 Chassis Assembly
The chassis assembly, shown in Figure 1-3, consists of:
•
Chassis
•
Backplane
The backplane is near the center of the system chassis. This allows for the
insertion and removal of system components from both the front and rear of
the system. Another advantage of this design is that component connections
are made with a small physical backplane.
